T.E. Maxson Wastewater Treatment Facility
The T.E. Maxson Facility treats an average of 70 million gallons per day of wastewater under NPDES Permit #TN0020729. The T.E. Maxson Facility is located at 2685 Steam Plant Road and began operation in 1975. It has gone through a series of major changes over the years. The treatment regime currently consists of coarse bar screens, grit removal, fine bar screens and primary treatment followed by high rate trickling filters, conventional activated sludge, and secondary clarification. Treated wastewater is discharged into the Mississippi River. The primary and waste activated sludge is sent to a covered lagoon system for anaerobic digestion. The digested sludge is dewatered with belt filter presses and the dewatered sludge cake is land applied on-site. The biogas generated by the covered lagoon system is both sold to a nearby utility and flared.
M.C. Stiles Wastewater Treatment Facility
The M.C. Stiles Facility treats an average daily flow of 80 million gallons of wastewater under Permit #TN0020711. The M.C. Stiles Facility is located at 373 Stiles Drive and began operation in 1977. The treatment regime consists of coarse bar screens, fine bar screens, grit removal, activated sludge contact-stabilization followed by secondary clarification and discharge into the Mississippi River. The waste activated sludge is sent to a covered lagoon system for anaerobic digestion. The digested sludge is dewatered with belt filter presses and the dewatered sludge cake is stored in a surface disposal facility on-site. The biogas generated by the covered lagoon system is sold to a nearby industry and used to fuel an electric generation operation on-site.
